Force Vertical Scrollbar?

I need assistance with a problem I cannot figure out. I have read over the helps and the forum posts on this issue and nothing suggested there seems to work. This issue affects two areas that I am working on. Both areas use fixed height grids. The first area involves a grid that uses a RowExpander. When I take a list that is too small for the container and expand all the row items such that it now extends beyond the height of the container, I do not get a scroll bar. The other area deals with a grid with a 100px height. The list I have in that grid extends beyond the limited height that I set, but I still get no scroll bar.

Is My Code Too Long?

I am not certain what kind of message you are trying to send me with that last post, Animal, although that shouldn't surprise me too much since I have had the chance now to see a number of your posts. You seem to have a gift for the cryptic answer.

If you are trying to tell me that I am being too verbose in my coding and to just list the affected areas, then just pay attention to the createGrid() function and the expander sections.
